Find out what to expect along the Boston Marathon course


Poland Spring Water and Lemon Lime Gatorade Endurance Formula stations will be set up along the course beginning at Mile Two. Note that the stations are staggered on each side of the road, i.e., the station on the right side will fall immediately prior to a similar station on the left side of the road. This is done to avoid runner gridlock, and we urge runners not to cross over from one side of the road to the other at the water stations.


Three Clif Shot Energy Gel stations will be located on the course: mile 11.8 on the Wellesley town line; mile 17 in Newton; and at mile 21.5 just after Boston College. Flavors include both caffeinated - Mocha & Citrus, and non-caffeinated - Vanilla & Razz.


Digital clocks, positioned at every mile and 5K mark, indicate the unofficial running time from the 10:00 a.m. start only. Signage indicates mile and 5K marks.


Runners unable to finish the race may stop for assistance and direction at one of the 26 American Red Cross first aid stations along the course. Sweep buses pick up runners at every Red Cross station with drop-off at the Finish Area medical tent. Aid stations along the course close at staggered times during the day. Finish area facilities officially close at approximately 5:30 p.m.


Runners still out on the course when officials determine that it is time to reopen the roads (approximately a 14:23 minute-per-mile pace) will be instructed to move to the right side of the road. Once roads begin to reopen to vehicular traffic, course infrastructure (such as timing systems, course clocks, medical stations, and water stations) will all begin to close and cease operation. Runners on the course after this time accept that they will be on their own and should plan accordingly. The B.A.A. will have a team of cyclists in the rear of the pack to assist runners who are at or slower than 14:23-minute-per-mile pace.


For your convenience and use during the race, the B.A.A. provides toilets at every water and Red Cross station, as well as at additional locations along the course. Please respect the communities through which the Boston Marathon runs by taking advantage of these facilities, if needed.


The B.A.A. will post every 5-kilometer split to its website. Family and friends can track your progress by logging in and entering your name or bib number. The “face” of the Boston Marathon website will change on race day and the process of how to search will be clear.
